These widgets are great, but ever since I upgraded to the new version of widgets, when I view them in gauge form, the rectangular form also appears, only the rectangular form doesn't actually work.
Great widget but to solve the desktop space problem it can be stacked behind the standard Yahoo Analog Clock. Set the clock to 50-60% transparency and the memory dial shows through. Lock the 2 widgets in place iStat on the bottom and the clock on top. Top right of the screen is a good spot. Cool!
